TECHNICAL FIELD

The disclosed embodiments relate generally to portable electronic devices, and more particularly, to portable devices for performing instant messaging.

BACKGROUND

As portable electronic devices become more compact, and the number of functions performed by a given device increase, it has become a significant challenge to design a user interface that allows users to easily interact with a multifunction device. This challenge is particular significant for handheld portable devices, which have much smaller screens than desktop or laptop computers. This situation is unfortunate because the user interface is the gateway through which users receive not only content but also responses to user actions or behaviors, including user attempts to access a device's features, tools, and functions.

Some portable communication devices (e.g., mobile telephones, sometimes called mobile phones, cell phones, cellular telephones, and the like) have resorted to adding more pushbuttons, increasing the density of pushbuttons, overloading the functions of the pushbuttons, or using complex menu systems to allow a user to access, store and manipulate data. These conventional user interfaces often result in complicated key sequences and menu hierarchies that must be memorized by the user.

Many conventional user interfaces, such as those that include physical pushbuttons, are also inflexible. This is unfortunate because it may prevent a user interface from being configured and/or adapted by either an application running on the portable device or by users. When coupled with the time consuming requirement to memorize multiple key sequences and menu hierarchies, and the difficulty in activating a desired pushbutton, such inflexibility is frustrating to most users.

Portable device-based Instant Messaging (IM) services are becoming increasingly popular. But most IM services on portable electronic devices have a rudimentary user interface. It is cumbersome to create instant messages on such devices. A user often needs to press a telephone keypad repeatedly to choose a character. It is also difficult to find and view previous instant messages. For example, it is inconvenient or even impossible for the user to view a series of previous messages with a particular user while composing a new message for that user.

IM services also typically do not allow the user to send telephony-based instant messages to multiple recipients in an intuitive manner. Interfaces for adding multiple recipients of an instant message are time consuming because they often require a user to repeatedly press many keys before all recipients are added. Furthermore, many of these interfaces do not allow the user to send a reply or another message to the set of multiple recipients without re-selecting all of the multiple recipients.

IM services also typically do not provide an intuitive interface for responding or viewing message when the device is in locked or unlocked mode. Many of the existing IM services also do not allow the user to view the message or a portion thereof without the user pressing a series of keys.

Accordingly, there is a need for portable multifunction devices with more transparent and intuitive user interfaces for instant messaging that are easy to use, configure, and/or adapt.

SUMMARY

The above deficiencies and other problems associated with user interfaces for portable devices are reduced or eliminated by the disclosed portable multifunction device. In some embodiments, the device has a touch-sensitive display (also known as a touch screen or a touch screen display) with a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch screen display.

Embodiments of a portable multifunction device, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device such as a mobile telephone that also contains other functions, such as PDA and/or music player functions.

The user interface may include a physical click wheel in addition to a touch screen or a virtual click wheel displayed on the touch screen. A click wheel is a user-interface device that may provide navigation commands based on an angular displacement of the wheel or a point of contact with the wheel by a user of the device. A click wheel may also be used to provide a user command corresponding to selection of one or more items, for example, when the user of the device presses down on at least a portion of the wheel or the center of the wheel. Alternatively, breaking contact with a click wheel image on a touch screen surface may indicate a user command corresponding to selection. For simplicity, in the discussion that follows, a portable multifunction device that includes a touch screen is used as an exemplary embodiment. It should be understood, however, that some of the user interfaces and associated processes may be applied to other devices, such as personal computers and laptop computers, which may include one or more other physical user-interface devices, such as a physical click wheel, a physical keyboard, a mouse and/or a joystick.

The device supports a variety of applications, such as one or more of the following: a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a blogging application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch screen. One or more functions of the touch screen as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch screen) of the device may support the variety of applications with user interfaces that are intuitive and transparent.

The user interfaces may include one or more soft keyboard embodiments. The soft keyboard embodiments may include standard (QWERTY) and/or non-standard configurations of symbols on the displayed icons of the keyboard, such as those described in U.S. patent application Ser. No. 11/459,606, “Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, and Ser. No. 11/459,615, “Touch Screen Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, the contents of which are hereby incorporated by reference in their entirety. The keyboard embodiments may include a reduced number of icons (or soft keys) relative to the number of keys in existing physical keyboards, such as that for a typewriter. This may make it easier for users to select one or more icons in the keyboard, and thus, one or more corresponding symbols. The keyboard embodiments may be adaptive. For example, displayed icons may be modified in accordance with user actions, such as selecting one or more icons and/or one or more corresponding symbols. One or more applications on the portable device may utilize common and/or different keyboard embodiments. Thus, the keyboard embodiment used may be tailored to at least some of the applications. In some embodiments, one or more keyboard embodiments may be tailored to a respective user. For example, one or more keyboard embodiments may be tailored to a respective user based on a word usage history (lexicography, slang, individual usage) of the respective user. Some of the keyboard embodiments may be adjusted to reduce a probability of a user error when selecting one or more icons, and thus one or more symbols, when using the soft keyboard embodiments.

The one or more buttons may include a push button (e.g., 206, FIG. 2). A quick press of the push button may disengage a lock of the touch screen 112 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 206) may turn power to the device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.

The touch-sensitive touch screen 112 provides an input interface and an output interface between the device and a user. The display controller 156 receives and/or sends electrical signals from/to the touch screen 112. The touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.

A touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen 112 and the display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on the touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen 112 and the user corresponds to a finger of the user.

The touch screen 112 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen 112 and the display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen 112.

A touch-sensitive display in some embodiments of the touch screen 112 may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, a touch screen 112 displays visual output from the portable device 100, whereas touch sensitive tablets do not provide visual output.

A touch-sensitive display in some embodiments of the touch screen 112 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference in their entirety herein.

The touch screen 112 may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 160 dpi. The user may make contact with the touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, the device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

In some embodiments, the device 100 may include a physical or virtual click wheel as an input control device 116. A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in the touch screen 112 by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller 160 as well as one or more of the modules and/or sets of instructions in memory 102. For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen 112 and the display controller 156, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.

The device 100 also includes a power system 162 for powering the various components. The power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

The device 100 may also include one or more optical sensors 164. FIGS. 1A and 1B show an optical sensor coupled to an optical sensor controller 158 in I/O subsystem 106. The optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module 143 (also called a camera module), the optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of the device 100, opposite the touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

The device 100 may also include one or more proximity sensors 166. FIGS. 1A and 1B show a proximity sensor 166 coupled to the peripherals interface 118. Alternately, the proximity sensor 166 may be coupled to an input controller 160 in the I/O subsystem 106. The proximity sensor 166 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 11/240,788, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices,” filed Oct. 24, 2006; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference herein in their entirety. In some embodiments, the proximity sensor turns off and disables the touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user's pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state.

The device 100 may also include one or more accelerometers 168. FIGS. 1A and 1B show an accelerometer 168 coupled to the peripherals interface 118. Alternately, the accelerometer 168 may be coupled to an input controller 160 in the I/O subsystem 106. The accelerometer 168 may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are which are incorporated herein by reference in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers.

In some embodiments, the software components stored in memory 102 may include an operating system 126, a communication module (or set of instructions) 128, a contact/motion module (or set of instructions) 130, a graphics module (or set of instructions) 132, a text input module (or set of instructions) 134, a Global Positioning System (GPS) module (or set of instructions) 135, and applications (or set of instructions) 136.

The operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

The communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by the RF circuitry 108 and/or the external port 124. The external port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Computer, Inc.) devices.

The contact/motion module 130 may detect contact with the touch screen 112 (in conjunction with the display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen 112, and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module 130 and the display controller 156 also detects contact on a touchpad. In some embodiments, the contact/motion module 130 and the controller 160 detects contact on a click wheel.

The graphics module 132 includes various known software components for rendering and displaying graphics on the touch screen 112, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like. An animation in this context is a display of a sequence of images that gives the appearance of movement, and informs the user of an action that has been performed (such as expanding a user-selected web-page portion to fill a browser window). In this context, a respective animation that executes an action, or confirms an action by the user of the device, typically takes a predefined, finite amount of time, typically between 0.2 and 1.0 seconds, and generally less than two seconds.

The text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, blogging 142, browser 147, and any other application that needs text input).

The GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 and/or blogger 142 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Each of the above identified modules and applications correspond to a set of instructions for performing one or more functions described above. These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. For example, video player module 145 may be combined with music player module 146 into a single module (e.g., video and music player module 152, FIG. 1B). In some embodiments, memory 102 may store a subset of the modules and data structures identified above. Furthermore, memory 102 may store additional modules and data structures not described above.

In some embodiments, the device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen 112 and/or a touchpad. By using a touch screen and/or a touchpad as the primary input/control device for operation of the device 100, the number of physical input/control devices (such as push buttons, dials, and the like) on the device 100 may be reduced.

The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates the device 100 to a main, home, or root menu from any user interface that may be displayed on the device 100. In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input/control device instead of a touchpad.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user may select one or more of the graphics by making contact or touching the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the contact may include a gesture, such as one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with the device 100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.

The device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, the menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on the device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI in touch screen 112.

In one embodiment, the device 100 includes a touch screen 112, a menu button 204, a push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, a Subscriber Identity Module (SIM) card slot 210, a head set jack 212, and a docking/charging external port 124. The push button 206 may be used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, the device 100 also may accept verbal input for activation or deactivation of some functions through the microphone 113.

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on a portable multifunction device 100.

FIG. 3 illustrates an exemplary user interface for unlocking a portable electronic device in accordance with some embodiments. In some embodiments, user interface 300 includes the following elements, or a subset or superset thereof:

-   -   Unlock image 302 that is moved with a finger gesture to unlock         the device;     -   Arrow 304 that provides a visual cue to the unlock gesture;     -   Channel 306 that provides additional cues to the unlock gesture;     -   Time 308;     -   Day 310;     -   Date 312; and     -   Wallpaper image 314.

In some embodiments, the device detects contact with the touch-sensitive display (e.g., a user's finger making contact on or near the unlock image 302) while the device is in a user-interface lock state. The device moves the unlock image 302 in accordance with the contact. The device transitions to a user-interface unlock state if the detected contact corresponds to a predefined gesture, such as moving the unlock image across channel 306. Conversely, the device maintains the user-interface lock state if the detected contact does not correspond to the predefined gesture. This process saves battery power by ensuring that the device is not accidentally awakened. This process is easy for users to perform, in part because of the visual cue(s) provided on the touch screen.

As noted above, processes that use gestures on the touch screen to unlock the device are described in U.S. patent application Ser. No. 11/322,549, “Unlocking A Device By Performing Gestures On An Unlock Image,” filed Dec. 23, 2005, and Ser. No. 11/322,550, “Indication Of Progress Towards Satisfaction Of A User Input Condition,” filed Dec. 23, 2005, which are hereby incorporated by reference in their entirety.

FIG. 4 illustrates an exemplary user interface for a menu of applications on a portable multifunction device in accordance with some embodiments. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator 402 for wireless communication;     -   Time 404;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Phone 138;         -   E-mail client 140, which may include an indicator 410 of the             number of unread e-mails;         -   Browser 147; and         -   Music player 146; and     -   Icons for other applications, such as:         -   IM 141;         -   Image management 144;         -   Camera 143;         -   Video player 145;         -   Weather 149-1;         -   Stocks 149-2;         -   Blog 142;         -   Calendar 148;         -   Calculator 149-3;         -   Alarm clock 149-4;         -   Dictionary 149-5;         -   User-created widget 149-6; and         -   Other applications (not shown)(e.g., map 154 and online             video 155).

In some embodiments, UI 400 displays all of the available applications 136 on one screen so that there is no need to scroll through a list of applications (e.g., via a scroll bar). In some embodiments, as the number of applications increase, the icons corresponding to the applications may decrease in size so that all applications may be displayed on a single screen without scrolling. In some embodiments, having all applications on one screen and a menu button enables a user to access any desired application with at most two inputs, such as activating the menu button 204 and then activating the desired application (e.g., by a tap or other finger gesture on the icon corresponding to the application).

In some embodiments, UI 400 provides integrated access to both widget-based applications and non-widget-based applications. In some embodiments, all of the widgets, whether user-created or not, are displayed in UI 400. In other embodiments, activating the icon for user-created widget 149-6 may lead to another UI (not shown) that displays the user-created widgets or icons corresponding to the user-created widgets. A user may activate a particular widget by gesturing on the corresponding name or icon.

In some embodiments, a user may rearrange the icons in UI 400, e.g., using processes described in U.S. patent application Ser. No. 11/459,602, “Portable Electronic Device With Interface Reconfiguration Mode,” filed Jul. 24, 2006, which is hereby incorporated by reference in its entirety. For example, a user may move application icons in and out of tray 408 using finger gestures.

In some embodiments, UI 400 includes a gauge (not shown) that displays an updated account usage metric for an account associated with usage of the device (e.g., a cellular phone account), as described in U.S. patent application Ser. No. 11/322,552, “Account Information Display For Portable Communication Device,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety.

FIG. 5 illustrates an exemplary user interface for listing instant message conversations on a portable electronic device in accordance with some embodiments. An instant message conversation includes a set of messages exchanged between a user of the portable electronic device and one or more other persons. In some embodiments, user interface 500 includes the following elements, or a subset or superset thereof:

-   -   402, 404, and 406, as described above;     -   “Instant Messages” or other similar label 502;     -   Names 504 of the persons a user has instant message         conversations with (e.g., Jane Doe 504-1) or the phone number if         the corresponding person's name is not available (e.g.,         408-123-4567 504-3);     -   Text 506 of the last message or a portion thereof in the         conversation (note that the last message could be the last one         either sent or received by the user);     -   Date 508 and/or time of the last message in the conversation;     -   Selection icon 510 that when activated (e.g., by a finger         gesture on the icon) initiates transition to a UI for the         corresponding conversation (e.g., FIG. 6A for Jane Doe 504-1);     -   Edit icon 512 that when activated (e.g., by a finger gesture on         the icon) initiates transition to a UI for deleting         conversations (e.g., FIG. 7);     -   Create message icon 514 that when activated (e.g., by a finger         gesture on the icon) initiates display of a user interface for         creating a new instant message and thus a new conversation; and     -   Vertical bar 516 that helps a user understand what portion of         the list of instant message conversations is being displayed.

FIG. 10 is a flowchart illustrating a process for displaying a list of instant message conversations on a portable electronic device's touch screen in accordance with some embodiments. Upon detecting a finger gesture (1002) (e.g., a finger tap 412 on the IM icon 141, FIG. 4), the IM module 141 identifies a set of IM conversations (1004) and displays them on the touch screen (1006). To be able to edit an existing conversation or launch a new conversation, the portable device may display an edit icon 512 and a create message icon 514, respectively, on the touch screen (1008). The portable device monitors user contact with the touch screen and acts accordingly (1010).

As shown in FIG. 5, the list of conversations may be displayed in a chronological order. The conversation with “Jane Doe” is at the top because it is the only conversation that includes at least one message generated today 508-1, which is assumed to be Jan. 29, 2006 in this example. In some embodiments, the conversations are ordered by the timestamp of the most recent message in each conversation. In some embodiments, a conversation including at least one message that has not been checked by the user is highlighted in the touch screen. For example, the third conversation in the list is displayed using boldfaced characters to suggest that the user has not checked the recent message sent by the person at the phone number 408-123-4567.

In some embodiments, the name 504 associated with an instant message conversation is determined by finding an entry in the user's contact list 137 that contains the phone number used by the instant message conversation. If no such entry is found, then just the phone number is displayed (e.g., 504-3). In some embodiments, if the other person sends messages from two or more different phone numbers, the messages may appear in the same conversation including the person's name if all the phone numbers used are found in the same entry (i.e., the entry for the other person) in the user's contact list 137. In some embodiments, the conversation includes messages sent from phone numbers and/or email addresses associated with the other person. In some embodiments, the messages sent by the other person include a first message sent from a first address associated with the other person and a second message sent from a second address associated with the other person that is different from the first address. In some embodiments, the first address is a telephone number and the second address is an email address. In some embodiments, the first and second addresses are two distinct telephone numbers. In some embodiments, the first and second addresses are two distinct email addresses.

In some other embodiments, if the other person sends messages from two or more different phone numbers, the messages may appear in different conversations corresponding to different numbers. The phone numbers or other identifiers are displayed next to the person's name to distinguish these conversations from each other.

In some embodiments, the name field of an instant message conversation includes names or other identifiers of multiple parties that participate in the conversation as message recipients and/or senders. If there is no room for displaying all the names, a selected subset of names is displayed with a symbol like “ . . . ” at the end, indicating that there are more parties in the conversation. By default, a message by the user of the portable electronic device is sent to all the parties of the conversation. For FIGS. 5-21 and the corresponding text, the IM conversations will be presumed to involve only two parties, the user and another person. For FIGS. 22A-34 and the corresponding text, the IM conversations will be presumed to involve more than two parties.

Automatically binning the instant messages into “conversations” (instant messages exchanged between the user of the device and a respective person or phone number) makes it easier for the user to carry on and keep track of instant message exchanges with multiple parties. As will be described below, the user is not only able to see the last message sent by the other party, the user can also visit old messages exchanged between the user and the other party.

In some embodiments, vertical bar 516 is displayed temporarily after an object is detected on or near the touch screen display (e.g., a finger touch is detected anywhere on the list of instant message conversations). In some embodiments, the vertical bar 516 has a vertical position on top of the displayed portion of the list that corresponds to the vertical position in the list of the displayed portion of the list. In some embodiments, the vertical bar 516 has a vertical length that corresponds to the portion of the list being displayed. In some embodiments, if the entire list of IM conversations can be displayed simultaneously on the touch screen 112, the vertical bar 516 is not displayed. In some embodiments, if the entire list of IM conversations can be displayed simultaneously on the touch screen 112, the vertical bar 516 is displayed with a length that corresponds to the length of the list display area (e.g., as shown in FIG. 5).

As noted above, the portable device monitors (1010) user contact with the conversation list. When the user swipes his finger or a stylus on the touch screen in a substantially vertical direction (1012), this user contact may be interpreted as a scrolling gesture. In some embodiments, the scrolling gesture is independent of the horizontal position of the user contact with the touch screen display. In some embodiments, the scrolling gesture is substantially independent of the horizontal position of the user contact with the touch screen display (e.g., one or more side regions of the touch screen display may be reserved for other functions, such as functions corresponding to icons, soft keys or application navigation functions, and not available for the scroll gesture). The portable electronic device, accordingly, scrolls the conversation list and displays a different portion of the conversation list (1020).

As shown in FIG. 5, the conversation list moves in a direction consistent with the scrolling gesture 517. If the scrolling gesture is downward (or upward), the conversation list also moves downward (or upward). Scrolling the conversation list downward will typically scroll the list to earlier entries in the list, until the first entry is reached (e.g., Jane Doe 504-1). But if the user does not have too many IM conversations, the portable electronic device may display the entire conversation list and the scrolling gesture has no effect.

If the user taps on the edit icon 512 using his finger or stylus (1018), the portable electronic device replaces the conversation list UI with a new UI that allows the user to edit the conversations. A more detailed description of the conversation editing feature is provided below in connection with FIGS. 7 and 16.

Similarly, if the user taps on the message creation icon 514 (1019), the portable electronic device replaces the conversation list UI with a new UI that allows the user to create a new instant message and therefore a new conversation. A more detailed description of this feature is provided below in connection with FIGS. 8A-8B, 9 and 19.

If the user taps on a particular conversation in the list (1014), the portable electronic device would interpret the tap as a gesture indicating that the user intends to check the messages associated with the user selected conversation. Accordingly, the portable electronic device replaces the conversation list UI shown in FIG. 5 with a conversation UI for a user-selected conversation (e.g., as shown in FIG. 6A).

FIGS. 6A through 6K illustrate an exemplary user interface for inputting text for an instant message in accordance with some embodiments.

In some embodiments, user interface 600A (FIG. 6A) includes the following elements, or a subset or superset thereof:

-   -   402, 404, and 406, as described above;     -   Name 504 corresponding to the phone number or email address used         in the instant message conversation (or the phone number itself         if the name is not available);     -   Instant messages icon 602 that when activated (e.g., by a finger         gesture on the icon) initiates transition to a UI listing         instant message conversations (e.g., UI 500);     -   Instant messages 604 from the other party, typically listed in         order along one side of UI 600A;     -   Instant messages 606 to the other party, typically listed in         order along the opposite side of UI 600A to show the back and         forth interplay of messages in the conversation;     -   Timestamps 608 for at least some of the instant messages;     -   Text entry box 612;     -   Return icon 614 that when activated (e.g., by a finger gesture         on the icon) initiates a new line in the message in text box         612;     -   Letter keyboard 616 for entering text in box 612;     -   Alternate keyboard selector icon 618 that when activated (e.g.,         by a finger gesture on the icon) initiates the display of a         different keyboard (e.g., 624, FIG. 6C);     -   Send icon 620 that when activated (e.g., by a finger gesture on         the icon) initiates sending of the message in text box 612 to         the other party (e.g., Jane Doe 504-1);     -   Shift key 628 that when activated (e.g., by a finger gesture on         the icon) capitalizes the next letter chosen on letter keyboard         616; and     -   Vertical bar 630 that helps a user understand what portion of         the list of instant messages in an IM conversation is being         displayed.

FIG. 11 is a flowchart illustrating a process for displaying a user selected instant message conversation upon detecting a predefined user contact with the portable electronic device's touch screen in accordance with some embodiments. In this example, the conversation with Jane Doe is displayed in response to a finger gesture 518 on the conversation with Jane Doe (FIG. 5).

Upon detecting the user selection of the conversation with Jane Doe (1102), IM module 141 identifies a set of instant messages 604 and 606 associated with the conversation (1104) and displays the instant messages in a message display region of the touch screen in a chronological order (1106). Because a user visiting an existing conversation may want to compose a new instant message to the other person, the portable electronic device also displays a message compose region on the touch screen (1108). In some embodiments, the message compose region includes a text box 612 displaying characters entered by the user, a send message icon 614, a letter keyboard 616, and a keyboard selector icon 618. The portable electronic device monitors the user contact with the touch screen and responds accordingly (1110).

In some embodiments, the portable electronic device receives an instant message while the user of the device is using another application, e.g., browsing a web page using the browser 147 or listening to music using the music player 146. In this case, the device may replace the user interface of an on-going application with a new user interface on the touch screen 112 or superimpose a new user interface on top of the user interface for the on-going application. FIG. 21 illustrates an exemplary user interface for alerting a user to a new instant message in accordance with some embodiments. This user interface may or may not suspend or terminate the on-going application. For example, the user may still listen to the music when this new user interface appears on the touch screen 112. This may be true even if the user subsequently chooses to activate the IM module 141 and respond to the new message.

In some embodiments, the new user interface (e.g., UI2100, FIG. 21) includes the following elements, or a subset or superset thereof:

-   -   the name 2102 of the person sending the instant message (e.g.,         Jane Doe), which may be determined by matching the phone number         or email address for the incoming instant message with a phone         number or email address in the user's contacts 137;     -   the newly received instant message or a portion thereof 2104         (e.g., “Do U want 2 . . . ”);     -   a first action icon 2106, e.g., “Ignore”; and     -   a second action icon 2108, e.g., “View.”         A user selection of the “Ignore” icon 2106 brings back the user         interface of the on-going application and the user can resume         the operation that was interrupted by the incoming message. A         user selection of the “View” icon 2108 may bypass the user         interface 500 and bring the user directly to the user interface         600A that includes the new instant message. The user can then         perform any message-related operations, as described below.

In some embodiments, the portable electronic device may receive an instant message while it is in the lock mode. In this case, the device may include a visual alert indicating the arrival of the new message in the user interface 300 and/or generate an audio alert through the device's speaker 111. If the user of the device unlocks the device's touch screen 112 in response to the visual and/or audio alert, the user may see user interface 600A (not user interface 400) on the touch screen. FIGS. 23A-23L, discussed below, also illustrate exemplary UIs for handling incoming instant messages.

As shown in FIG. 6A, the instant messages 604 from Jane Doe may be displayed on the left side of the message display region with the most recent message (e.g., 604-2) towards the bottom. The messages sent by the user to Jane Doe are on the opposite side of the display region. The messages' relative vertical locations correspond to the order in which these messages are exchanged between the user of the device and Jane Doe. Selected timestamps 608 further indicate when these messages are exchanged. In some embodiments, a timestamp is displayed near the message it is associated with. If the message display region does not have enough room to display the timestamp of every message currently in the message display region, the device may display timestamps for a subset of the messages, e.g., a timestamp 608-1 corresponding to the message 604-1 at the top of the message region and a timestamp 608-2 corresponding to the message 606-2 at the bottom of the message region. In some embodiments, the device may display more timestamps for messages in the middle if, e.g., the time gap between the two messages is above a predefined threshold. From the instant messages, the user can easily capture the topic of the conversation. If necessary, the user can browse the other old messages not currently on display by applying a scrolling gesture 610 on the message display region (1112). In response, the portable electronic device scrolls the set of message conversations (1124). In some embodiments, the scrolling gesture is independent of the horizontal position of the user contact with the touch screen display. In some embodiments, the scrolling gesture is substantially independent of the horizontal position of the user contact with the touch screen display, as described above.

In some embodiments, the device highlights certain portions of incoming and outgoing messages using, e.g., underlines, distinct font sizes or styles, and/or colors. Typically, the highlighted portions are deemed to have special connotations such as phone numbers, URLs, stock tickers, or contacts' names. These highlighted message portions may be user-selectable. For example, a user finger gesture on the highlighted portion “apple.com” of the message 604-2 causes the activation of the browser 147, which then brings up the home page of the website www.apple.com. Similarly, a user finger gesture on a telephone number activates the phone 138 and initiates a call to the telephone number.

In some embodiments, a vertically downward scrolling gesture scrolls the conversation downward, thereby showing older messages in the conversation. In some embodiments, a vertically upward scrolling gesture scrolls the conversation upward, thereby showing newer, more recent messages in the conversation. In some embodiments, as noted above, the last message in the conversation (e.g., 606-2) is displayed in the list of instant message conversations 500 (e.g., 506-1).

In some embodiments, vertical bar 630 is displayed temporarily after an object is detected on or near the touch screen display (e.g., a finger touch is detected anywhere on the list of instant messages). In some embodiments, the vertical bar 630 has a vertical position on top of the displayed portion of the list that corresponds to the vertical position in the list of the displayed portion of the list. In some embodiments, the vertical bar 630 has a vertical length that corresponds to the portion of the list being displayed. For example, in FIG. 6A, the vertical position of the vertical bar 630 indicates that the bottom of the list of messages is being displayed (which correspond to the most recent messages) and the vertical length of the vertical bar 630 indicates that roughly half of the messages in the conversation are being displayed.

In response to the user's finger gestures on different letter keys in the keyboard (1114), a new instant message is composed in the text box 612. A more detailed description of this composition process is provided below in connection with FIG. 12. In some embodiments, the keyboard 616 in FIG. 6A has only 26 English characters due to the touch screen's limited size. To enter characters such as digits, punctuation and other special symbols, the user needs to tap on the keyboard selector icon 618 (1120) and/or the shift key icon 628 (1116) to bring in additional keyboards or switch the existing keyboard to a different display mode (e.g., from upper/lower case to lower/upper case). More detailed descriptions of these processes are provided below in connection with FIGS. 13 and 14, respectively. After completing the new message, the user taps on the send message icon 614 to transmit the message to the other participant of the conversation (1118). A more detailed description of the sending process is provided below in connection with FIG. 15.

FIG. 12 is a flowchart illustrating a process for displaying a user-entered character and word suggestions, if any, in accordance with some embodiments. Upon detecting a user selection of a letter key (1202), the portable electronic device displays the user-selected letter in the text box 612 (1204). To expedite the process of composing the new message, the portable electronic device may determine if it can offer any word suggestions based on the user input (1206). To do so, the portable electronic device may apply linguistics-based algorithms (e.g., as described in U.S. patent application Ser. No. 11/549,624, titled “Method, System, and Graphical User Interface for Text Entry with Partial Word Display” filed Oct. 13, 2006, which is hereby incorporated by reference in its entirety) to the user input and display one or more related words from its database (1208).

As shown in FIG. 6B, user interface 600B (FIG. 6B) includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 602, 604, 606, 608, 612, 614, 616, 618, and 620         as described above; and     -   word suggestion area 622 that provides a list of possible words         to complete the word fragment being typed by the user in text         box 612.

In this example, based on the user-entered string “vacat”, the portable electronic device displays three possible words, “vacant”, “vacate”, and “vacation”, in the area 622. The user can choose any of them by finger tapping on a respective word icon. Alternatively, the user can ignore all the computer-suggested words by tapping on the icon that exactly matches his input. In some embodiments, the portable electronic device also saves the user input as a new word in its database. Subsequently, when the user enters the same string or a subset thereof, the portable electronic device may display this new word as one of the word suggestions. In some embodiments, the word suggestion area does not appear in UI 600B until after a predefined time delay (e.g., 2-3 seconds) in text being entered by the user. In some embodiments, the word suggestion area is not used or can be turned off by the user. In some embodiments, a suggested word (e.g., 644 FIG. 6H, discussed below) is displayed next to the user-entered string (e.g., just above or just below the string), rather than in a separate area 622.

If there is no suggestion by the portable electronic device or if the option is turned off, the portable electronic device resumes monitoring the user contact with the touch screen and acts accordingly (1210).

Additional description of providing word suggestions can be found in U.S. patent application Ser. No. 11/620,642, “Method, System, and Graphical User Interface for Providing Word Recommendations,” filed Jan. 5, 2007, the content of which is hereby incorporated by reference in its entirety.

As noted above, the keyboard 616 may not include all the characters the user would like to enter. There are different approaches to bringing in additional characters. For example, as shown in FIG. 6B, the user can tap on the keyboard selector icon 618 to replace the current letter keyboard 616 with a new keyboard that includes a different set of characters such as digits and/or punctuation.

FIG. 13 is a flowchart illustrating a process for displaying respective keyboards upon detecting a user contact with a keyboard selection icon in accordance with some embodiments. In response to a user selection of the keyboard selector 618 (1302), the portable electronic device checks what type of keyboard is requested (1304). Depending on the type of the requested keyboard, the portable electronic device displays a letter keyboard (1308) or non-letter keyboard (1306). In some embodiments, the meaning of the user contact with the keyboard selector icon 618 depends on the keyboard's current display mode. Following the display of the requested keyboard, the portable electronic device then resumes monitoring the user contact with the touch screen (1310).

As shown in FIG. 6C, after a user finger gesture on the keyboard selector icon 618 in FIG. 6B, a new user interface 600C is rendered on the touch screen with the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 602, 604, 606, 608, 612, 614, 620, and 622 as         described above;     -   Alternate keyboard 624, which may be made up primarily of digits         and punctuation, with frequently used punctuation keys (e.g.,         period key 631, comma key 633, question mark key 635, and         exclamation point key 637) made larger than the other keys;     -   Letter keyboard selector icon 626 that when activated (e.g., by         a finger gesture on the icon) initiates the display of a letter         keyboard (e.g., 616, FIG. 6A); and     -   Shift key 628 that when activated (e.g., by a finger gesture on         the icon) initiates display of yet another keyboard (e.g., 639,         FIG. 6D).

Note that the non-letter keyboard selector 618 in FIG. 6B is now replaced with the letter keyboard selector 626 in FIG. 6C. In some embodiments, the period key 631 and the comma key 633 are located near the keyboard selector icon 626 to reduce the distance that a user's finger needs to travel to enter the oft-used period and comma.

But the alternate keyboard 624 may not be all-inclusive. For example, it may not have any arithmetic operators such as “+”, “−”, “*”, or “/”. A finger gesture on the keyboard selector 626 brings back the letter keyboard 616, not any new keyboards. In some embodiments, the user may tap on another multi-function key, e.g., the shift key 628, to bring in additional keyboards.

In some embodiments, like the keyboard selector icons (618, 626), the shift key 628 has different meanings in different contexts. FIG. 14 is a flowchart illustrating a process for interpreting the meaning of a particular user contact with the shift key 628 in accordance with some embodiments. The portable electronic device detects user selection of the shift key (1402). The portable electronic device checks what keyboard is currently displayed on the touch screen (1404). If the current one is a letter keyboard, a finger gesture on the shift key triggers the portable electronic device to switch its display mode of the subsequent user-entered letters from uppercase to lowercase or vice versa (1406).

Referring back to FIG. 6B, in some embodiments, the portable electronic device, by default, only displays the first letter “h” of the first word “how” in uppercase. If the user wants to enter another uppercase letter in the same sentence, he can tap on the shift key 628. As a result, the shift key 628 is displayed in a visually different manner (e.g., with a different color or shading) after the finger gesture. In some embodiments, the shift key 628 returns to the lowercase mode after the user enters the next letter in uppercase. If the user wants to enter a sequence of uppercase letters, he can maintain the finger contact with the shift key 628 for a predefined extended period of time (e.g., 1-3 seconds) until the shift key 628 has a new appearance. In some other embodiments, the shift key 628 stays in the uppercase mode for all subsequent user-entered letters until another finger gesture is detected on the shift key 628.

Returning now to FIG. 14, the user contact with the shift key 628 has a different meaning if the current keyboard is a non-letter keyboard (e.g., the alternate keyboard 624 in FIG. 6C). Because none of the characters in the keyboard 624 have two different display modes, the portable electronic device replaces the keyboard 624 with another non-letter keyboard 639 (1408) and then waits for the next user contact with the touch screen (1410).

FIG. 6D is a screenshot of the corresponding user interface 600D, which includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 602, 604, 606, 608, 612, 614, 620, 622, 626, 628         as described above; and     -   Another alternate keyboard 639, which may be made up primarily         of symbols and punctuation, with frequently used punctuation         keys (e.g., period key 631, comma key 633, question mark key         635, and exclamation point key 637) made larger than the other         keys.

Like the keyboard 624, none of the characters in the keyboard 639 have two different display modes. In some embodiments, the user can tap again on the shift key 628 to bring in more alternate keyboards with more special characters or symbols. In some embodiments, the user can tap again on the shift key 628 to return to the alternate keyboard 624. At any time, the user can also switch back to the letter keyboard by tapping on the keyboard selection icon 626.

Additional description of selecting soft keyboards can be found in U.S. patent application Ser. No. 11/553,431, “Method, System, and Graphical User Interface for Selecting a Soft Keyboard,” filed Oct. 26, 2006, the content of which is hereby incorporated by reference in its entirety.

After completing a new message, the user sends the message by activating (e.g., with a finger gesture) the send message icon 614. FIG. 6E depicts such a user interface 600E that includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 602, 604, 606, 608, 612, 614, 616, 618, and 620,         as described above; and     -   New instant message 606-3 sent to the other party.

In some embodiments, this user finger gesture triggers an animation of the new message moving from the text box 612 to the side of the message display region showing messages sent by the user of the device. For example, when the user activates a send key (e.g., either 614), the text in text box 612 “pops” or otherwise comes out of the box and becomes part of the string of user messages 606 to the other party. The black arrows in FIG. 6E illustrate an animated formation of a quote bubble 606-3. In some embodiments, the size of the quote bubble scales with the size of the message. In some embodiments, a sound is also made when the message is sent, such as a droplet sound, to notify the user.

FIG. 15 is a flowchart illustrating a process for sending an instant message to a respective recipient in accordance with some embodiments. In response to a user selection of the send message icon (1502), the portable electronic device checks if there is any user input in the text box (1504). If not, it may simply ignore the user's finger gesture on the send icon or display an error message on the touch screen (1508). In some embodiments, the visual appearance of the send icon 614 is changed (e.g., dimmed) if there is no user input in the text box.

If there is any user input in the text box (1504, yes), the portable electronic device may optionally conduct a spell check of the user input (1506). If there are any spelling errors (1510, yes), an error message and/or word suggestions are displayed on the touch screen for the user to choose (1512). If there are no spelling errors, the portable electronic device sends the message and may also animate the movement of the new message from the text box into the message display region (1514). The portable electronic device then monitors the user contact with the touch screen (1516).

In some embodiments, keys in keyboards 616 (FIGS. 6A, 6B, 6E-6K), 624 (FIG. 6C), and/or 639 (FIG. 6D) briefly change shape, shade and/or color when touched/activated by a user to help the user learn to activate the desired keys. In some embodiments, a user selection of any key on the touch screen by a finger gesture is accompanied by a sound for the same purpose. In some other embodiments, different sounds are associated with different types of keystrokes to indicate what keys have been “pressed” by the user. In some embodiments, an outline or shaded area corresponding to the user's finger contact is shown on the keyboard to help train the user.

In some embodiments, a user can delete an instant message from a conversation by finger tapping on the corresponding quote bubble in the message display region. The portable electronic device, in response, grays out the bubble and pops up a small window on the touch screen. The small window may include a “Yes” icon and a “No” icon. If the user reaffirms his decision of deleting the message by finger tapping on the “Yes” icon, the portable electronic device removes the bubble from the message display region. But if the user chooses the “No” icon, the quote bubble resumes its normal appearance.

In some embodiments, user interface 600F (FIG. 6F) includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 612, 614, 616, 618, 620, and 628, as described         above;     -   Recipient input field 632 that when activated (e.g., by a finger         tap on the field) receives and displays the phone number of the         recipient of the instant message (or the recipient's name if the         recipient is already in the user's contact list);     -   Add recipient icon 634 that when activated (e.g., by a finger         tap on the icon) initiates the display of a scrollable list of         contacts (e.g., 638, FIG. 6G); and     -   Cancel icon 636 that when activated (e.g., by a finger tap on         the icon) cancels the new instant message.

In some embodiments, user interface 600G (FIG. 6G) includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 616, 618, 620, 628, 632, 634, and 636, as         described above;     -   Scrollable list 638 of contacts that match the input in         recipient input field 632; and     -   Vertical bar 640 that helps a user understand how many items in         the contact list that match the input in recipient input field         632 are being displayed.

In some embodiments, list 638 contains contacts that match the input in recipient input field 632. For example, if the letter “v” is input, then contacts with either a first name or last name beginning with “v” are shown. If the letters “va” are input in field 632, then the list of contacts is narrowed to contacts with either a first name or last name beginning with “va”, and so on until one of the displayed contacts is selected (e.g., by a tap on a contact in the list 638).

In some embodiments, a user can scroll through the list 638 by applying a vertical swipe gesture 642 to the area displaying the list 638. In some embodiments, a vertically downward gesture scrolls the list downward and a vertically upward gesture scrolls the list upward,

In some embodiments, vertical bar 640 is displayed temporarily after an object is detected on or near the touch screen display (e.g., a finger touch is detected anywhere on the list 638). In some embodiments, the vertical bar 640 has a vertical position on top of the displayed portion of the list that corresponds to the vertical position in the list of the displayed portion of the list. In some embodiments, the vertical bar 640 has a vertical length that corresponds to the portion of the list being displayed.

In some embodiments, user interfaces 600H (FIG. 6H) and 600I (FIG. 6I) include the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 612, 614, 616, 618, 620, 628, 632, 634, and 636,         as described above;     -   Suggested word 644 adjacent to the word being input;     -   Suggested word 646 in the space bar in keyboard 616; and/or     -   Insertion marker 656 (e.g., a cursor, insertion bar, insertion         point, or pointer).

In some embodiments, activating suggested word 644 (e.g., by a finger tap on the suggested word) replaces the word being typed with the suggested word 644. In some embodiments, activating suggested word 646 (e.g., by a finger tap on the space bar) replaces the word being typed with the suggested word 646. In some embodiments, a user can set whether suggested words 644 and/or 646 are shown (e.g., by setting a user preference).

In some embodiments, a letter is enlarged briefly after it is selected (e.g., “N” is enlarged briefly after typing “din” in FIG. 6H) to provide feedback to the user.

In some embodiments, user interfaces 600J (FIG. 6J) and 600K (FIG. 6K) include the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 612, 614, 616, 618, 620, 628, 632, 634, 636, and         656 as described above; and     -   Expanded portion 650 of graphics that helps a user adjust the         position of an expanded insertion marker 657 (sometimes called         an “insertion point magnifier”);     -   Expanded insertion marker 657; and     -   Vertical bar 658 that indicates what portion of an instant         message including multiple lines of text is being displayed.

In some embodiments, a finger contact 648-1 on or near the insertion marker 656 initiates the display of insertion point magnifier 650 and expanded insertion marker 657-1. In some embodiments, as the finger contact is moved on the touch screen (e.g., to position 648-2), there is corresponding motion of the expanded insertion marker (e.g., to 657-2) and the insertion point magnifier 650. Thus, the insertion point magnifier 650 provides an efficient way to position a cursor or other insertion marker using finger input on the touch screen. In some embodiments, the magnifier 650 remains visible and can be repositioned as long as continuous contact is maintained with the touch screen (e.g., from 648-1 to 648-2 to even 648-3).

In some embodiments, a portable electronic device displays graphics and an insertion marker (e.g., marker 656, FIG. 6I) at a first location in the graphics on a touch screen display (e.g., FIG. 6I). In some embodiments, the insertion marker 656 is a cursor, insertion bar, insertion point, or pointer. In some embodiments, the graphics comprise text (e.g., text in box 612, FIG. 6I).

A finger contact is detected with the touch screen display (e.g., contact 648-1, FIG. 6I). In some embodiments, the location of the finger contact is proximate to the location of the insertion marker. In some embodiments, the location of the finger contact is anywhere within a text entry area (e.g., box 612, FIG. 6I).

In response to the detected finger contact, the insertion marker is expanded from a first size (e.g., marker 656, FIG. 6I) to a second size (e.g., marker 657-1, FIG. 6J) on the touch screen display, and a portion (e.g., portion 650-1, FIG. 6J) of the graphics on the touch screen display is expanded from an original size to an expanded size.

In some embodiments, the portion of the graphics that is expanded includes the insertion marker and adjacent graphics. In some embodiments, after the insertion point and the portion of the graphics are expanded, graphics are displayed that include the insertion marker and adjacent graphics at the original size and at the expanded size.

Movement of the finger contact is detected on the touch screen display (e.g., from 648-1 to 648-2, FIG. 6J).

The expanded insertion marker is moved in accordance with the detected movement of the finger contact from the first location (e.g., 657-1, FIG. 6J) to a second location in the graphics (e.g., 657-2, FIG. 6J).

In some embodiments, the portion of the graphics that is expanded changes as the insertion marker moves from the first location to the second location (e.g., from 650-1 to 650-2, FIG. 6J). In some embodiments, the portion of the graphics that is expanded is displayed in a predefined shape. In some embodiments the portion (e.g., 650, FIG. 6J) of the graphics that is expanded is displayed in a circle. In some embodiments, the expanded insertion marker 657 is within the circle.

In some embodiments, the detected movement of the finger contact has a horizontal component on the touch screen display and a vertical component on the touch screen display. In some embodiments, moving the expanded insertion marker 657 in accordance with the detected movement of the finger contact includes moving the expanded insertion marker and the expanded portion of the graphics in accordance with the horizontal component of motion of the finger contact if the finger contact moves outside a text entry area without breaking contact. For example, in FIG. 6I, if the finger contact moves from 648-2 (inside the text entry area 612) to 648-3 (in the keyboard area), the expanded insertion point 657 and the expanded portion 650 of the graphics may move horizontally along the lower portion of the text entry area in accordance with the horizontal component of the movement from 648-2 to 648-3 (not shown).

In some embodiments, moving the expanded insertion marker in accordance with the detected movement of the finger contact includes moving the expanded insertion marker in a first area of the touch screen that includes characters entered using a soft keyboard (e.g., text box 612, FIG. 6J), wherein the soft keyboard is located in a second area of the touch screen that is separate from the first area (e.g., keyboard 616, FIG. 6J).

In some embodiments, the expanded insertion marker is contracted from the second size to the first size if finger contact with the touch screen display is broken (e.g., insertion marker 656, FIG. 6K). In some embodiments, the contracting includes an animation of the expanded insertion marker 657 shrinking into the insertion marker 656 at the second location.

In some embodiments, the expanded portion 650 of the graphics is contracted if finger contact with the touch screen display is no longer detected for a predetermined time.

A graphical user interface on a portable electronic device with a touch screen display comprises an insertion marker and graphics. In response to detecting a finger contact 648 with the touch screen display, the insertion marker is expanded from a first size 656 to a second size 657, and a portion 650 of the graphics is expanded. In response to detecting movement of the finger contact on the touch screen display, the expanded insertion marker is moved in accordance with the detected movement of the finger contact from a first location 657-1 in the graphics to a second location 657-2 in the graphics.

As noted above in connection with FIG. 6E, a user finger selection of the send key 614 triggers an animation of the message moving from the text box 612 to the message display region. In some embodiments, prior to sending the message, the size of the text box expands as text is entered (e.g., from one line of text in FIG. 6H to two lines of text in FIG. 6I). In some embodiments, the text box 612 does not have enough room for displaying the entire message if it has too many lines of text (as indicated by the short vertical bar 658). When a quote bubble containing the multi-line message comes out of the text box 612, it may gradually grow its size until a predefined condition is met (e.g., the bubble has enough room to contain the entire message and/or the size of the bubble reaches a threshold that is statically or dynamically determined by the device based on the number of existing messages in the conversation). For example, if the text box shows 3 lines of a 10 line instant message, then the quote bubble may grow from a 3 line quote bubble to a 10 line quote bubble during the animation that moves the message from the text box 612 to the message display region.

Additional description of insertion marker positioning can be found in U.S. patent application Ser. No. 11/553,436, “Method, System, And Graphical User Interface For Positioning An Insertion Marker In A Touch Screen Display,” filed Oct. 26, 2006, the content of which is hereby incorporated by reference in its entirety.

Besides deleting individual messages from a conversation, an entire conversation may be deleted via edit icon 512 in FIG. 5. FIG. 7 illustrates an exemplary user interface for deleting an instant message conversation in accordance with some embodiments. In some embodiments, user interface 700 includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 504, 506, 508, 510, as described above;     -   Delete icons 702;     -   Remove icon 704; and     -   Done icon 706.

FIG. 16 is a flowchart illustrating a process for displaying a list of instant message conversations for editing in accordance with some embodiments. Upon detecting a user selection of the edit icon 512 (1602), the portable electronic device associates a delete icon 702 with each conversation (1604) (e.g., a delete icon 702 appears next to each conversation). Additionally, the portable electronic device may replace the edit icon 512 with a done icon 706 (1606) and monitor user contact with the touch screen (1608).

If the user swipes his finger or stylus on the touch screen in a substantially vertical direction (1610), the portable electronic device scrolls the conversation list (1616). If a user activates a delete icon (e.g., with a finger gesture), the portable electronic device continues the deletion process for the corresponding conversation. A more detailed description of an exemplary conversation removal process is provided below in connection with FIGS. 17 and 18. But if the user touches the done icon, the portable electronic device removes all the delete icons 702 from the touch screen and brings back the conversation list UI as shown in FIG. 5.

FIG. 17 is a flowchart illustrating a process for editing a user selected instant message conversation in accordance with some embodiments. Upon detecting a user selection of the delete icon associated with a conversation (1702), the portable electronic device changes the delete icon's appearance (e.g., rotating the selected delete icon 702-4, FIG. 7, by 90 degrees) (1704). The portable electronic device associates a confirmation icon (e.g., remove icon 704) with the selected conversation (1706). In some embodiments, during the editing process, at most one confirmation icon at a time is displayed on the touch screen. Depending on the next user contact with the touch screen (1708), the portable electronic device may perform different operations to the conversation list. For example, the device may scroll the list up/down in response to a scrolling gesture by the user (1710, 1718). The device may bring back the conversation list UI in response to a finger gesture on the done icon (1714).

FIG. 18 is a flowchart illustrating a process for removing a user selected instant message conversation or exiting a conversation edit mode in accordance with some embodiments. If the user selects the confirmation icon (1712, 1802), the portable electronic device removes the conversation from the touch screen (1804). If the removed conversation is not the last one in the list, the portable electronic device may shift other conversations upward to fill the space left by the removed conversation (1806). A finger gesture on the modified delete icon 702-4 or, in some embodiments, anywhere on the touch screen besides the confirmation icon 704 (1716, 1803) indicates that the user decides not to delete the conversation. Accordingly, the portable electronic device changes the delete icon back to its original appearance (1805) and removes the confirmation icon from the touch screen (1807).

Following the operation 1806 or 1807, the portable electronic device resumes monitoring the user contact with the touch screen (1808). For example, the user may activate the done icon 706 (1814) by tapping on it with a finger when the user has finished deleting IM conversations and the device returns to UI 500. The user may delete another conversation by activating its associated delete icon (1812). If there is a long list of conversations that fill more than the screen area, the user may scroll through the list using vertically upward and/or vertically downward gestures 708 on the touch screen (1810, 1816).

This conversation removal process, which requires multiple gestures by the user on different parts of the touch screen (e.g., delete icon 702-4 and confirmation icon 704 are on opposite sides of the touch screen) can reduce the chance that a user accidentally deletes a conversation or other similar item.

Referring again to FIG. 5, a user may start a new conversation with another person by activating the message creation icon 514 (e.g., with a finger tap or other gesture). FIG. 19 is a flowchart illustrating a process for displaying a list of contacts from which a user chooses to send an instant message in accordance with some embodiments. After detecting the user selection of the message creation icon 514 (FIG. 5), and, in some embodiments, add icon 634 (FIG. 6F) (1902), the portable electronic device identifies a set of contacts from the user's address book or the equivalent because it does not know to whom this new conversation is directed (1904). Next, the portable electronic device displays the identified contacts on the touch screen (1908). In some embodiments, the portable electronic device displays multiple icons on the touch screen in addition to the contact list (1909), such as the group contacts icon, the first name and last name icons, the alphabet list icons, the cancel icon, and the other number icon. A more detailed description of these icons is provided below in connection with FIGS. 8A and 8B. After rendering the contact list and the additional icons, the portable electronic device then monitors the user contact with the touch screen (1910).

FIGS. 8A and 8B illustrate an exemplary user interface for a contact list in accordance with some embodiments. In some embodiments, user interfaces 800A and 800B include the following elements, or a subset or superset thereof:

-   -   402, 404, 406, as described above;     -   Groups icon 802 that when activated (e.g., by a finger gesture         on the icon) initiates display of groups of contacts;     -   First name icon 804 that when activated (e.g., by a finger         gesture on the icon) initiates an alphabetical display of the         user's contacts by their first names (FIG. 8B);     -   Last name icon 806 that when activated (e.g., by a finger         gesture on the icon) initiates an alphabetical display of the         user's contacts by their last names (FIG. 8A);     -   Alphabet list icons 808 that the user can touch to quickly         arrive at a particular first letter in the displayed contact         list;     -   Cancel icon 810 that when activated (e.g., by a finger gesture         on the icon) initiates transfer back to the previous UI (e.g.,         UI 500); and     -   Other number icon 812 that when activated (e.g., by a finger         gesture on the icon) initiates transfer to a UI for entering a         phone number for instant messaging, such as a phone number that         is not in the user's contact list (e.g., UI 900, FIG. 9).

As described in U.S. patent application Ser. No. 11/322,547, “Scrolling List With Floating Adjacent Index Symbols,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety, the user may scroll through the contact list using vertically upward and/or vertically downward gestures 814 on the touch screen.

If the next user contact is such a scrolling gesture 814 (1912) or a finger gesture on one of the first name icon 804, the second name icon 806 and the alphabet list icons 808 (1914), the portable electronic device modifies the contacts currently on display (1920). Although the contact list may be shared by multiple applications on the same portable device (e.g., email, phone, and instant messaging), a user selection of a name in the contact list in this context will be used for IM service because the contact list was requested from within the IM application. Here the contact list is being shown in connection with user activation of the message creation icon 514 in the IM application 141.

If the portable electronic device detects a finger gesture on one person's name or other identifier in the contact list (1916), the portable electronic device displays a message compose region for a message to the selected contact (1108, FIG. 11) and displays a conversation UI as shown in FIG. 6A. In some embodiments, if there is an existing conversation between the user and the selected person, the portable electronic device merges the new conversation into the existing one by displaying messages associated with the existing conversation.

If the portable electronic device detects a user gesture on the cancel icon 810 (1918), the portable electronic device aborts the process of creating the new conversation and brings back the conversation list shown in FIG. 5 (1006, FIG. 10).

In some embodiments, if the portable electronic device detects a finger gesture on the other number icon 812 (1919), typically a new conversation with a person not in the contact list is initiated. Accordingly, the portable electronic device may render a new user interface for the user to enter the person's contact information that is going to be used by the new conversation.

FIG. 20 is a flowchart illustrating a process for launching a new conversation using a new phone number in accordance with some embodiments. Upon detecting user selection of the other number icon (2002), the portable electronic device provides a contact information display region (2004) and a contact information compose region (2006) on the touch screen. The contact information may be a phone number or an email address for IM service. The contact information display region includes a text box 906 for displaying the user-entered contact information. The contact information compose region includes a keyboard 624 for the user to enter such contact information. The device monitors user contact with the touch screen (2008). If the user activates the cancel icon (2012), the portable electronic device aborts the process of creating a new conversation and returns to the conversation list UI shown in FIG. 5. If the user input is a letter or number (2010), the portable electronic device displays it in the text box (2014).

FIG. 9 illustrates an exemplary user interface for entering a phone number for instant messaging in accordance with some embodiments. In some embodiments, user interface 900 includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 602, and 624, as described above;     -   Cancel icon 902 that when activated (e.g., by a finger gesture         on the icon) initiates transfer back to the previous UI (e.g.,         UI 800A or UI 800B);     -   Save icon 904 that when activated (e.g., by a finger gesture on         the icon) initiates saving the entered phone number in the         instant messages conversation list (e.g., UI 500) and displaying         a UI to compose an instant message to be sent to the entered         phone number (e.g., UI 600A); and     -   Number entry box 906 for entering the phone number using         keyboard 624.

Note that the keyboard displayed may depend on the application context. For example, the UI displays a soft keyboard with numbers (e.g., 624) when numeric input is needed or expected. The UI displays a soft keyboard with letters (e.g., 616) when letter input is needed or expected.

FIGS. 22A-22Q illustrate exemplary user interfaces for creating and sending telephony-based instant messages to multiple recipients and for receiving and responding to replies to such messages in accordance with some embodiments. The user interfaces in FIGS. 22A-22Q are described in more detail below. In addition, the user interfaces in FIGS. 22A-22Q are used to illustrate the processes described below with reference to FIGS. 24-29.

FIG. 22A illustrates an exemplary user interface 2200A for displaying instant messaging conversations on a portable electronic device in accordance with some embodiments. The UI 2200A in FIG. 22A shows a list of instant message conversations, with entries listing conversations with two individuals (Tom and an unknown person with phone number 310-123-4567). The IM conversations listed in FIG. 22A do not include any group conversations. In some embodiments, UI 2200A includes the following elements, or a subset or superset, thereof:

-   -   402, 404, and 406, as described above;     -   “Instant Messages” or “Text Messages” or other similar label         2202;     -   Names 2204 of the persons with whom the user has instant message         conversations (e.g., Tom 2204-1); when the name of the other         party is not available, the displayed name may be the phone         number of the other party (e.g., 310-123-4567 2204-2);     -   an unread message indicia 2206 that indicates messages that have         not been read;     -   Text 2207 of the last message or a portion thereof in the         conversation (note that the last message could be the last one         either sent or received by the user);     -   Date 2208 and/or time of the last message in the conversation;     -   Selection icon 2210 that when activated (e.g., by a finger         gesture on the icon) initiates transition to a UI for the         corresponding conversation;     -   Edit icon 2212 that when activated (e.g., by a finger gesture on         the icon) initiates transition to a UI for deleting         conversations (e.g., UI 700, FIG. 7); and     -   Create message icon 2222 that when activated (e.g., by a finger         gesture on the icon) initiates transition to the users contact         list (e.g., FIG. 8A).

FIGS. 22B-22D illustrate exemplary user interfaces for selecting multiple recipients of an instant message in accordance with some embodiments. These Figures illustrate using finger gestures to address an instant message to multiple recipients (e.g., to Mike Van Os, Tom, and Allen Cook) using a method similar to that described above with respect to FIGS. 6G and 6H. In particular, finger gesture 2231 in UI 2200B, FIG. 22B, selects Mike Van Os as a message recipient; finger gesture 2248, FIG. 22C in UI 2200C, selects Tom as another message recipient; and finger gesture 2250 in UI 2200D, FIG. 22D, selects Allen Cook as yet another message recipient.

In some embodiments, user interface 2200B (FIG. 22B) includes the following elements, or a subset or superset, thereof:

-   -   402, 404, and 406 as described above;     -   Recipient input field 2232 that when activated (e.g., by a         finger tap on the field) receives and displays the phone number         of the recipient(s) of the instant message (or the recipient's         name if the recipient is already in the user's contact list);     -   Add recipient icon 2234 that when activated (e.g., by a finger         tap on the icon) initiates the display of a scrollable list of         contacts (e.g., 2239, FIG. 22B);     -   Scrollable list 2239 of contacts (e.g., where a vertical swipe         gesture 2242 upwards to scroll the list up, and downward to         scroll the list down);     -   Text box 2212 that when activated (e.g., by a finger tap on the         field) displays a message compose region (FIG. 6H).     -   Vertical bar 2240 that helps a user understand how many items in         the contact list that match the input in recipient input field         2232 are being displayed in the scrollable list 2239; and     -   Cancel icon 2236 that when activated (e.g., by a finger tap on         the icon) cancels the composing of a new instant message.

In some embodiments, user interfaces 2200C and 2200D (FIGS. 22C and 22D) includes the following elements, or a subset or superset, thereof:

-   -   402, 404, 406, 2212, 2214, and 2234 as described above; and     -   Recipient icons 2244, 2246, and 2252.

FIG. 22E illustrates an example of a user interface 2200E for composing an instant message to multiple recipients after user selection of the recipients in accordance with some embodiments. FIG. 22E shows a first message sent to Mike Van Os, Tom, and Allen Cook (e.g., “We'll meet at AMC at 8 PM.”).

User interface 2200E includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406 as described above;     -   “Outgoing” or other similar label 2258 indicating that the         message is being sent from the device to others;     -   Multi-recipient identifier 2261 identifying all recipients of         the instant message;     -   Details icon 2262 that when activated allows the user to access         detailed contact information of a corresponding recipient;     -   Instant messages icon 2254 that when activated transitions to a         UI showing a list of instant messaging conversations (e.g. FIG.         22F);     -   Group conversation indicia 2256 which indicates that the message         is a part of a group conversation;     -   Clear icon 2260 that when activated (e.g. by a finger gesture on         the icon) clears the message entry text box;     -   a text box 2212 that when activated (e.g., by a finger tap on         the field) displays a message compose region (e.g., FIG. 6H);     -   the most recent outgoing message 2264; and     -   a send icon 2214 that when activated, sends the message to the         selected recipients.

FIG. 22F illustrates an example of a user interface 2200F for displaying a list of instant messaging conversations including a group conversation and a response to an instant message in accordance with some embodiments. In particular, FIG. 22F shows the list of instant message conversations after the first message has been sent and after one of the recipients (Tom) has replied. The most recent entry in the instant message conversation between the user and Tom is now “I will bring a friend with me,” rather than “Hola.”

In some embodiments, user interface 2200F includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 2212, 2222 as described above;     -   an unread message indicia 2206 that indicates messages that have         not been read;     -   group conversation indicia 2266 that indicates the conversation         (next to which the indicia 2266 is displayed) is a group         conversation; and     -   a time indicator 2269 that indicates the time at which a last         message of the group conversation was sent.

FIG. 22G-H illustrates examples of user interfaces for displaying a set of outgoing messages between the user and one or more parties and for composing a message to one or more parties in accordance with some embodiments. FIG. 22G shows, in a user interface 2200G, the instant message conversation between the user and Tom after Tom has replied to the first instant message of a group conversation with Mike Van Os, Tom, and Allen Cook. The messages appear in chronological order, with the most recent message (“I will bring a friend with me”) closest to the text input box. FIG. 22H shows, in a user interface 2200H, a second instant message 2272 being composed by the user. In this example, the message “BTW, the new AMC in Cupertino” will be sent to all the other parties in the group conversation, Mike Van Os, Tom, and Allen Cook, when the user activates the Send icon 2214.

In some embodiments, user interface 2200G includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 2212 and 2214 as described above; and     -   a set of messages 2264 between the user and a recipient(s).

In some embodiments, user interface 2200H includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 2214, 2254, 2256, 2258, 2260 as described above;     -   a details icon 2262 that when activated (e.g. by finger tap         gesture on the icon) replaces a multi-recipient identifier 2261         with a set of contact icons (e.g., 2285 FIG. 22N), each contact         icon representing one of the multiple recipients.     -   a multi-recipient identifier 2261 that shows all recipients of         the outgoing message;     -   a new outgoing message 2272 to the other parties (recipients) in         the group conversation; and     -   a set of messages 2264 between the user and a recipient(s).

FIG. 22I-22K illustrate examples of user interfaces for displaying an error message after experiencing a problem sending a message to one or more of the recipients in accordance with some embodiments. FIGS. 22I and 22J illustrate an example of an error message that is displayed, if there is a problem sending the message to one or more of the recipients, while the user is using an instant messaging application. FIG. 22K illustrates an example of an error message that is displayed, if there is a problem sending the message to one or more of the recipients, while the user is using a non-instant messaging application.

In some embodiments, user interfaces 2200I-2200K (FIGS. 22I-22K) may include the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 2254, 2256, 2258, 2260, 2261, 2262, and 2264 as         described above;     -   Label indicating error and error message 2276 indicating a         communication error in connection with sending the new outgoing         message;     -   a cancel icon 2278 that when activated (e.g., by a finger tap         gesture) cancels or postpones the sending of the message;     -   a try again icon 2280 that when activated (e.g., by a finger tap         gesture) resends the message to at least one of the multiple         recipients; and     -   the outgoing message 2272 is displayed with an appearance         distinct from the other outgoing messages, if any, in the         conversation.

FIG. 22L illustrates an example of a user interface 2000L for replying to an instant message and for displaying a list of instant messages in a group conversation in accordance with some embodiments. FIG. 22L shows the “group conversation” with Mike Van Os, Tom, and Allen Cook after the second instant message has been sent to the group. In some embodiments, a “group conversation” includes only outbound telephony-based instant messages from the user to a group selected by the user. Thus, “group conversations” are actually a collection of one-way outbound messages and not two-way exchanges amongst the group for telephony-based instant messages.

In some embodiments, user interface 2200L may include the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 2212, 2214, 2254, 2256, 2258, 2260, 2261 and 2262         as described above;     -   the group conversation including the first 2264 and second         instant message 2272 sent to the group.

FIG. 22M illustrates an example of a user interface 2200M for accessing detailed information on recipients of the group conversation while composing a message to the group. FIG. 22M shows how the user can access details on the members of the group conversation.

In some embodiments, UI 2200M includes the following elements, or a subset or superset thereof:

-   -   one or more contact icons 2285 that when activated displays         contact information of a corresponding recipient in the multiple         recipients; and     -   a Hide icon 2286 that when activated will replace the set of         contact icons with a multi-recipient identifier (e.g., 2261 FIG.         22L).

FIG. 22N illustrates an example of a user interface 2200N for displaying detailed information of a user selected contact, such as a user selected member of a group conversation. The user of the device may navigate to user interface 2200N of FIG. 22N by performing a finger gesture 2274 (FIG. 22M) on a contact icon 2285 in a group conversation user interface (e.g., UI 2300M, FIG. 22M).

In some embodiments, UI 2200N includes the following elements, or a subset or superset thereof:

-   -   Graphic representing the contact;     -   Name of the contact; and     -   Phone numbers associated with the contact

FIGS. 22O and 22P illustrate examples of user interfaces for displaying instant messaging conversations on a portable electronic device in accordance with some embodiments. In some embodiments, UI 2200O and UI 2200P include elements already discussed with respect to user interface 2200A (FIG. 22A) and UI 2200F (FIG. 22F). In particular, FIG. 22O shows the list of instant message conversations after a second message (“BTW, the new AMC in Cupertino”) has been sent to a group of recipients and before any of the recipients have replied. The group conversation with the most recent message has been moved to the top of the user's list of instant message conversations.

As shown here, in some embodiments, in the list of instant messages conversations outbound messages to a group only appear in the corresponding group conversations. Such messages do not appear as the most recent message in the corresponding individual conversations in the list of instant message conversations. For example, in FIG. 22O, “BTW, the new AMC in Cupertino” appears with the group conversation, but not with the individual conversation with Tom.

FIG. 22P shows an example of a list of instant message conversations after the second message has been sent and after Mike Van Os has replied to the second message. In this example, Mike Van Os did not have a pre-existing instant messaging conversation with the user, so a new individual conversation has been started with Mike Van Os. Replies to outbound messages in a group conversation are either added to existing individual instant messaging conversations (e.g., a conversation with Tom) or used to initiate new individual instant messaging conversations (e.g., a new conversation with Mike Van Os). In some embodiments, replies are not incorporated into the group conversation, which only contains outbound messages.

FIG. 22Q illustrates an example of a user interface 2200Q for displaying a set of outgoing messages between the user and one or more parties and for composing a message to one or more parties in accordance with some embodiments. FIG. 22Q shows an example of a user interface displaying the new instant messaging conversation between the user and Mike Van Os after Mike Van Os has replied to the second instant message in the group conversation. As shown here, in some embodiments, the conversation includes the outbound messages that were sent to Mike Van Os as part of the group conversation, as well as the reply(s) by Mike Van Os.

In some embodiments, UI 2200Q includes the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 2212, 2214, and 2254 as described above; and     -   a set of messages 2264, 2272, 2283 between the user and a         recipient including any messages (e.g., messages 2264, 2272)         that are part of a group conversation received by the recipient.

FIG. 24 is a flow diagram for illustrating an example of a process for adding multiple recipients to an instant message through finger gestures in accordance with some embodiments. In some embodiments, the device allows the user to compose and send a telephony-based instant message to multiple recipients. An instant message conversation, in the following context, includes a set of messages between a user of the portable device and other person(s) based on Short Messaging Service (SMS), Multimedia Messaging Service (MMS), Enhanced Messaging Service (EMS), or other telephony-based communication protocol.

The multiple recipients in the group conversation are selected by a process 2400 in which:

-   -   in response to detecting a finger gesture on an add recipient         icon (e.g., 2234 FIG. 22B), the device displays (2402) a list of         contacts on the touch screen;     -   in response to detecting a finger swipe gesture (e.g., 2242,         FIG. 22B) on the contact list, the device scrolls (2404) the         list of contacts on the touch screen; and     -   in response to detecting a finger gesture (e.g., 2231 FIG. 22B,         2248 FIG. 22C, 2250 FIG. 22D) on a contact in the list of         contacts, the device adds the contact to the multiple         recipients, and generates a corresponding recipient icon (e.g.,         2246 FIG. 22C, 2252 FIG. 22D) in a message recipient field on         the touch screen display (2406).

The device repeats (2408) the process above until all of the multiple recipients are selected.

In some embodiments, the list of contacts is narrowed to contacts corresponding to the letters inputted. For example, if the letter “v” is inputted, the list of contacts is narrowed to contacts having a name that starts with a “v” (e.g., FIG. 22B). The narrowed list of contacts include, for example, first names or last names that begin with a “v,” (e.g., “Vivian” or “Mike Van Os”) or businesses or other entities stored in the contacts list that have a name that begins with a “v.” Similarly, as shown in FIG. 22C, if the user inputs a “t,” the list of contacts is narrowed to contacts corresponding to “t,” which includes last names, first names, and other entities (e.g., “Typhoon”) that start with a “t.”

In some embodiments, multiple recipients in the message can be selected by directly entering contact information through the soft keyboard. In response to one or more finger gestures on one or more keys corresponding to one or more letters on a soft keyboard displayed on the touch screen display, the device displays the one or more letters in the message recipient field on the touch screen display.

FIG. 25 is a flow diagram showing an exemplary method 2500 for displaying a list of instant messaging conversations including a group conversation and for sending a new outgoing message to multiple recipients in the group conversation in accordance with some embodiments. Method 2500 occurs at a portable electronic device with a touch screen display.

The device displays (2502) a list of instant messaging conversations (e.g., UI 2200F) including a group conversation (e.g., 2270 FIG. 22F). The group conversation includes a first multi-recipient identifier (e.g., 2268) and a group conversation indicia (e.g., 2266).

As previously discussed, in some embodiments incoming messages or responses to the group conversation are not considered to be part of the group conversation, and hence are not designated with a group conversation indicia (e.g., 2266). For example, Tom's message 2271 (FIG. 22F) is a response to the user's group conversation 2270 (as shown in FIG. 22F, Tom was a recipient of the outgoing message.). Because responses to the group conversation are not considered to be part of the group conversation, Tom's response 2271 is not accompanied by a group conversation indicia (e.g., 2266).

In response to detecting a user selection of the group conversation (e.g., 2270 FIG. 22F), the device displays (2504) a set of outgoing messages (e.g., 2264 FIG. 22H) from a user of the device to multiple recipients in a chronological order and also displays a second multi-recipient identifier (e.g., 2261 FIG. 22H).

In some embodiments, the first multi-recipient identifier (e.g., 2268 FIG. 22F) identifies a subset, but not all, of the multiple recipients, while the second multi-recipient identifier (e.g., 2261 FIG. 22H) identifies all of the multiple recipients. For example, the first multi-recipient identifier (e.g., 2268 FIG. 22F) may be an abbreviated representation (e.g., “Mike Van Os & others”) of the recipients. In some embodiments, if the identifiers of the message recipients in the second multi-recipient identifier field (e.g., 2261 FIG. 22E) are too long and/or numerous to be displayed in the display region that is used for listing message recipients, a scroll bar may be displayed to allow the user to scroll through a list of the message recipients, enabling the user to view all of the message recipients.

The device receives (2506) a new outgoing message for the group conversation entered by the user of the device through the touch screen display. In some embodiments, the new outgoing messages are short messaging service (SMS), multimedia messaging service (MMS), or enhanced messaging service (EMS) messages.

In response to detecting a user request to send the new outgoing message to the multiple recipients, the device sends (2508) the new outgoing message to the multiple recipients in the group conversation. Also in response to detecting a user request to send the new outgoing message to the multiple recipients, the device appends (2508) the new outgoing message to the set of outgoing messages displayed on the touch screen display. For example, in FIG. 22H, after the user requests to send the new outgoing message (e.g., user gesture on the “Send” icon 2214) the device sends the new outgoing message to the multiple recipients and appends the new outgoing message (e.g., 2272) to the set of outgoing messages (2264, FIG. 22L), as shown in FIG. 22L.

In some embodiments, the appending of the new outgoing message to the set of the outgoing messages displayed on the touch screen occurs before the sending of the new outgoing message to multiple recipients. These two parts of operation 2508 are independent of each other and can happen in any order.

FIG. 26 is a flow diagram illustrating an example of a process for displaying an error message indicating a communication error when sending the new outgoing message and for resending the message after an error in accordance with some embodiments.

In some embodiments, the device displays (2602) an error message (e.g., 2276 FIG. 22I) indicating a communication error in connection with sending the new outgoing message to at least one of the multiple recipients, displays (2602) a resend-message icon (e.g., 2280) on the touch screen display, and resends the new outgoing message to the at least one of the multiple recipients in response to a user selection (e.g., finger tap gesture) of the resend-message icon (e.g., 2280).

In some embodiments, the device displays (2604) the error message (e.g., 2276 FIG. 22I) and the resend-message icon (e.g., 2280) before appending the new outgoing message to the set of outgoing messages. For example, in FIG. 22I, the device displays an error message in connection with sending the new outgoing message, but has not yet appended the message to the set of outgoing messages (e.g., 2264 FIG. 22I).

In some embodiments, the device displays (2606) the error message (e.g., 2276 FIG. 22J) and the resend-message icon (e.g., 2280) after appending the new outgoing message (e.g., 2272) to the set of outgoing messages (e.g., 2264).

In some embodiments, after appending the new outgoing message (e.g., 2272 FIG. 22L) to the set of outgoing messages (e.g., 2264), the device displays (2608) the list of conversations (e.g., FIG. 22O) in response to detecting a user request to return to the list of conversations (e.g., user gesture on the “Instant Messages” icon 2254, FIG. 22L).

After appending the new outgoing message (e.g., 2272 FIG. 22L) to the set of outgoing messages (e.g., 2264 FIG. 22L), the device also updates (2608) the display of the group conversation in the list of conversations (e.g., UI 2200O FIG. 22O) by replacing a previously-displayed outgoing message (e.g., 2270 FIG. 22F) associated with the group conversation with the new outgoing message (e.g., 2292 FIG. 22O). For example, in FIG. 22O, the message “BTW, the new AMC in Cupertino” now replaces the previously displayed outgoing message “We'll meet at AMC at 8 pm.”

In some embodiments, the message with the error bears a different appearance than other messages in the conversation (e.g. dotted lines, different colors). After successfully resending the message, the appearance of the message (e.g., 2272) will change to indicate success (e.g., removal of dotted lines) (FIG. 22L.) Additionally, in FIG. 22L, the text box 2212 is available for sending of more messages to the group after successfully resending the message.

FIG. 27 is a flow diagram illustrating an example of a process for displaying an error message in connection with sending the new outgoing message to at least one of the multiple recipients when a non-messaging application is being used while sending the outgoing message in accordance with some embodiments.

The group conversation and the new outgoing message are part of an instant messaging application on the portable electronic device. The portable electronic device includes a plurality of applications in addition to the instant messaging application, and in this example one or more of the plurality of additional applications are used while sending the new outgoing message (2702). For example, the user may switch to a non-messaging application after sending a message.

The device displays (2704) on top of a non-messaging application an error message (e.g., 2276 FIG. 22K) indicating a communication error in connection with sending the new outgoing message to at least one of the multiple recipients and a resend-message icon (e.g., 2280) on the touch screen display. For example, in FIG. 22K, the error message 2276 is displayed on top of a non-messaging application “Camera Roll.”

The device resends (2706) the new outgoing message to the at least one of the multiple recipients in response to detecting a user selection of the resend-message icon (e.g., 2280).

After the device resends the new outgoing message (2706), the device ceases (2708) to display the error message on top of the non-messaging application. In some embodiments, in response to user selection of the Cancel icon (e.g., 2278), the device also ceases to display the error message on top of the non-messaging application.

FIG. 28 is a flow diagram illustrating an example of a process for replying to an existing conversation between the user of the device and the recipient, and for generating a new conversation between the user of the device and the recipient of the message in accordance with some embodiments.

In some embodiments, the device receives (2802) a reply message from a recipient in the multiple recipients in response to the new outgoing message. In this example, there is an existing conversation between the user of the device and the recipient, and the existing conversation is listed in the list of conversations. For example, in FIG. 22F, the device receives a reply message (e.g., 2271) from a recipient (Tom) in the multiple recipients (e.g., in FIG. 22E, the recipients were Tom, Allen Cook, and Mike) in response to the new outgoing message (e.g., 2270). As shown in FIG. 22A, there is already an existing conversation between the user of the device and Tom.

In some embodiments, the device updates (2804) the existing conversation between the user of the device and the recipient by appending the reply message to previous messages in the existing conversation between the user of the device and the recipient. For example, in some embodiments, the device will update the existing conversation between Tom and the user of the device by appending the user's reply message to previous messages between the user and Tom.

In some embodiments, in response to detecting a user selection (e.g., finger tap gesture) of the existing conversation between the user of the device and the recipient (e.g., the conversation with Tom, shown in FIG. 22F), the device displays (2806) the reply message and the previous messages in the existing conversation between the user of the device and the recipient. For example, in response to user selection of Tom's reply message 2271 in the user interface shown in FIG. 22F, the device displays (FIG. 22G) Tom's reply message “I will bring a friend with me” and the previous messages, “We'll meet at AMC at 8 PM” and “Hola” in the existing conversation between the user of the device and Tom.

In some embodiments, the previous messages in the existing conversation between the user of the device and the recipient includes each of the set of outgoing messages in the group conversation. For example, in UI 2200G (FIG. 22G), the previous messages includes the outgoing messages in the group conversation (e.g. “We'll meet at AMC at 8 pm”).

The previous messages in the existing conversation between the user of the device and the recipient include messages, if any, that are not in the set of outgoing messages in the group conversation. For example, in UI 2200G (FIG. 22G), the previous messages include messages not in the group conversation (e.g., “Hola”).

The device may receive (2808) a reply message from a recipient in the multiple recipients in response to the new outgoing message, wherein there is no existing conversation between the user of the device and the recipient in the list of conversations. For example, the user of the device may receive a message from Mike Van Os (e.g., 2294 FIG. 22P). As previously discussed, Mike Van Os is a recipient of the “BTW, the new AMC in Cupertino” message 2292 that is part of a group conversation (see FIG. 22E). In this example, there is no existing conversation between the user and Mike in the list of conversations (see FIG. 22A, FIG. 22F, and FIG. 22P).

In some embodiments, when the device receives a reply message from a recipient in the multiple recipients in response to the new outgoing message, wherein there is no existing conversation between the user of the device and the recipient in the list of conversations, the device generates (2810) a new conversation between the user of the device and the recipient that includes the reply message. In the example shown in FIG. 22P, since there is no existing conversation between Mike and the user, the device generates a new conversation between the user and Mike, including Mike's reply message “Sorry that I can't come tonight . . . ” 2294.

In some embodiments, in response to detecting a user selection of the new conversation between the user of the device and the recipient (e.g., 2294 FIG. 22P), the device displays (2816) the reply message (e.g., “Sorry that I can't come tonight . . . ” FIG. 22Q).

In some embodiments, generating the new conversation between the user of the device and the recipient further includes inserting (2812) into the new conversation (between the user of the device and the recipient) each of the set of outgoing messages in the group conversation. In some embodiments, generating the new conversation between the user of the device and the recipient also includes appending (2814) the reply message from the recipient to the inserted set of outgoing messages in the new conversation between the user of the device and the recipient. For example, in FIG. 22Q, the set of outgoing messages in the group conversation (“We'll meet at AMC at 8 PM” 2264 and “BTW, the new AMC in Cupertino” 2272) is inserted into the new conversation between the user and Mike. The reply message from Mike (“Sorry that I can't come tonight. Next time!” 2283) is also appended to the inserted set of outgoing messages.

FIG. 29 is a flow diagram illustrating an example of a process for revealing and hiding contact details in accordance with some embodiments. In response to detecting user selection (e.g., finger tap gesture) of the group conversation (e.g., 2290 FIG. 22P), the device displays (2902) a details icon (e.g., 2262 FIG. 22L) adjacent to the second multi-recipient identifier 2261 (FIG. 22L).

In response to detecting user selection of the detail icon (e.g., 2262), the device replaces (2904) a multi-recipient identifier (e.g., “Mike Van Os, Tom, Allen Cook,” 2261 FIG. 22L) with a set of contact icons 2285 (e.g., FIG. 22M), each contact icon representing one of the multiple recipients. For example, in UI 2200M, Allen Cook, one of the multiple recipients of the message, is represented by the contact icon 2285-2 “Allen Cook.”

In some embodiments, one of the set of contact icons is a telephone number. For example, this may occur if the recipient is not on the device's contact list (not shown on drawings).

In response to detecting user selection of the details icon (e.g., 2262 FIG. 22L), the device also replaces (2906) the details icon with a hide detail icon (e.g., 2286 FIG. 22M).

In response to detecting user selection of one of the set of contact icons (e.g., 2285-2), the device displays (2908) contact information of a corresponding recipient in the multiple recipients. For example, in response to user selection (e.g., 2274) of the “Allen Cook” contact icon 2285-2, the device displays UI 2200N (FIG. 22N) which contains the contact information of “Allen Cook.”

In some embodiments, email addresses and other information associated with the contact that is not relevant to sending instant messages are grayed-out in the user interface showing the selected recipient's contact information (not shown in FIG. 22N).

In response to detecting user selection of the hide detail icon (e.g., 2286 FIG. 22M), the device replaces (2910) the set of contact icons 2285 with the multi-recipient identifier 2261 (e.g., “Mike Van Os, Tom, Allen Cook” FIG. 22L).

FIGS. 23A-23L illustrate exemplary user interfaces for displaying incoming instant messages while the device is in locked and unlocked mode in accordance with some embodiments. The user interfaces in FIGS. 23A-23L are described in more detail below. In addition the user interfaces in FIGS. 23A-23L are used to illustrate the processes described with reference to FIGS. 30A, 30B and 31A-31C below.

FIG. 23A illustrates an exemplary user interface for unlocking a portable electronic device in accordance with some embodiments. In some embodiments, user interface 2300A includes the following elements, or a subset or superset thereof:

-   -   An unlock image 302 that is moved with a finger gesture         (sometimes called the unlock gesture) to unlock the device;     -   Arrow 304 that provides a visual cue to the unlock gesture;     -   Channel 306 that provides additional cues to the unlock gesture;     -   Time 308;     -   Day 310;     -   Date 312; and     -   Wallpaper image 314.

FIG. 23B illustrates an example of a user interface UI 2300B for displaying, while device remains locked (also called in locked mode), an incoming message from a party to the user of the device and for displaying an unlock icon or view icon in accordance with some embodiments. In particular, FIG. 23B shows an incoming message from Jane sent to the user of the device. A portion of the message is displayed because the message is longer than a predefined length. The “slide to unlock” icon 306 of FIG. 23A also changes to a “slide to view” icon 2214.

In some embodiments, UI 2300B includes the following elements, or a subset or superset thereof:

-   -   302, 304, 308, 310, 312, and 314 as described above;     -   name of the party 2210 that sent the incoming message to the         user of the device;     -   a portion of the incoming message 2212;     -   a long message indicia 2211 indicating the incoming message is         longer than a predefined length; and a     -   slide to view image 2214 (in place of the slice to unlock image         306, of UI 2300A, FIG. 23A) that in response to a gesture (e.g.,         a finger sliding gesture), immediately displays a set of         messages between the user of the device and the party in a         chronological order.

FIG. 23C illustrates an exemplary user interface 2300C for displaying a message alert on the touch screen display in accordance with some embodiments. In particular, FIG. 23C shows an incoming message as an alert. If the user ignores the message shown in UI 2300B for at least a predetermined period of time, FIG. 23B, the displayed message of UI 2300B is reduced to a message alert as shown on FIG. 23C, and the “slide to view” icon 2214 changes back to the “slide to unlock” icon 306. The user is determined to have ignored the message shown in UI 2300B for at least the predetermined period of time if no user request to view the incoming message (e.g. a finger gesture 2213 on the view icon 2214 FIG. 23B) is detected within a predetermined period of time.

In some embodiments, UI 2300C includes the following elements, or a subset or superset thereof:

-   -   302, 304, 306, 308, 310, 312, and 314 as described above; and     -   a message alert 2302 that includes the identifier of the party         (e.g., “Jane Doe”) and a time indicator (e.g., “9:14 am, today”)         for the incoming message.

FIG. 23D illustrates an example of a user interface 2300D allowing the user to respond to the incoming message. In this example, FIG. 23D shows an instant message conversation between the user and Jane Doe. If the user chooses to view the message (from FIG. 23B), the device displays a message response UI 2300D (FIG. 23D), which allows the user to respond to Jane's message. In this example, the user's responds with a message having the text “Great idea!” The messages appear in chronological order with the user's response at the end.

In some embodiments, UI 2300D displays the incoming message in its entirety 2216, the user's response to the incoming message 2215, and elements already discussed with respect to UI 2200G (FIG. 22G).

FIG. 23E illustrates an example of a user interface 2300E for displaying, while the device is unlocked, an incoming message having a length that is less than or equal to a predefined length according to some embodiments. In this example, FIG. 23E shows an incoming message received while the device is in unlocked mode and while a non-messaging application (e.g., Camera Roll) is in use. The message 2218 is displayed on top of the non-messaging application. Here, the device displays the entire message because the incoming message is shorter than the predefined length. The UI 2300E includes icons 2220, 2222 that enable the user to either reply to the message or close the message.

In some embodiments, user interface 2300E includes the following elements, or a subset or superset thereof:

-   -   the incoming message in its entirety 2218;     -   a close icon 2220 that when activated ceases the display of the         incoming message or a portion thereof; and     -   a reply icon 2222 that when activated immediately displays a set         of messages between the user and the party in a chronological         order (see, for example, UI 2300H, FIG. 23H).

FIG. 23F-23G illustrate examples of user interfaces for displaying a list of instant messaging conversations between the user and other parties, and for displaying the status of the incoming message. In some embodiments, user interfaces 2300F-2300G include elements already discussed with respect to UI 2200A (FIG. 22A) and UI 2200F (FIG. 22F). FIG. 23F shows an example of a list of instant messaging conversations. There are conversations listed for Patrick, Jane Doe, and Tom. An unread message indicia 2206 is displayed next to the list entries for the conversations with Patrick and Tom. If the user ignores the message pop-up on FIG. 23E (user does not select either close or reply), Patrick's message will be marked as unread because the device assumes that the user did not read the message.

FIG. 23G shows another example of a list of instant messaging conversations, similar to the list in FIG. 23F. However, in this example, only the list entry for the conversation with Tom has an unread message indicia next to it. The list entry for the conversation with Patrick does not have an unread indicia next to it because, in this example, A) the last message from Patrick was displayed in its entirety (as shown in FIG. 23D), and B) the user chose to close the message, for example by touching the close icon 2220 shown in FIG. 23E. Because Patrick's entire message was displayed (FIG. 23E) and because the user chose to close the message, the device assumes that the user read the message, and therefore does not mark the message as unread.

FIG. 23H illustrates an example of a user interface 2300H for composing a reply message and for displaying a set of messages including the incoming message. The user interface 2300H is displayed, for example, after the user chooses (e.g., by touching with a finger) the “Reply” icon 2222 in UI 2300E (FIG. 23E). In this example, FIG. 23H shows a plurality of the most recent messages from the instant messaging conversation between the user and Patrick, and a soft keyboard for entering a reply message. The UI 2300H enables the user to respond to Patrick's message. In some embodiments, user interface 2300H includes elements already discussed with respect to UI 2300D (FIG. 23D), including an incoming message 2223-1 and reply to the incoming message 2223-2.

FIG. 23I illustrates an example of a user interface 2300I for displaying, while the device is unlocked, an incoming message that is longer than a predefined length according to some embodiments. UI 2300I shows a portion 2225 of an incoming message when the device is unlocked and a non-messaging application is in use. Only a portion of the message is displayed because the message is longer than a predefined length. The user can read the entire message by either scrolling the message with a scroll bar 2232, or by selecting the View icon 2230. The user can also select the Close icon 2228 to close the displayed message. Note, that the sender of the incoming message in this example is designated by a phone number and not a contact name. The phone number from which a message is received may be displayed when the phone number is not found in the user's contact list, or if the phone number is found in the user's contact list by the contact list entry does not include a name.

In some embodiments, UI 2300I includes the following elements, or a subset or superset thereof:

-   -   a View icon 2230 that when activated immediately displays a set         of messages between the user of the device and the party in a         chronological order. The displayed set of messages includes the         incoming message;     -   a Close icon 2228 that when activated within a predetermined         period of time of the message (or message portion) first being         displayed, causes the incoming message or a portion thereof to         no longer be displayed;     -   a long message indicia (e.g., an ellipsis, “ . . . ”) 2229; and     -   a scroll indicator 2232 that when activated allows the user to         scroll through the message.

FIG. 23J illustrate an example of a user interface 2300J for displaying a list of instant messaging conversations between the user and other parties, and for displaying the status of the incoming message. In this example, FIG. 23J shows a list of instant messaging conversations between the user and other parties that is displayed after the user chooses to close the message shown in FIG. 23I without scrolling through the message, or when the user does not respond to the message pop-up within a predetermined period of time. The conversation that includes the incoming message (from 408-123-4567) is designated with an unread message indicia. It is noted that, because only a portion of the incoming message was displayed, and the user did not scroll through the remainder of the message, the user did not read the entire incoming message. In some embodiments, user interface 2300J includes elements already discussed with respect to UI 2200A (FIG. 22A), UI 2200F (FIG. 22F), UI 2200P (FIG. 22P) and UI 2200Q (FIG. 22Q).

FIG. 23K illustrates an example of a user interface 2300K for displaying a set of messages between the user of the device and the party that sent the incoming message in a chronological order according to some embodiments. UI 2300K includes the text of the entire incoming message 2223. UI 2300K of FIG. 23K is display, for example, when the user selects the view icon 2230 in UI 2300I, FIG. 23I. In FIG. 23K, the user can view all messages, or at least all recent messages, between the user and the 408-123-4567 party. UI 2300K optionally includes a scroll bar when the messages in the conversation do not fit on the touch screen display. To reply to the incoming message, or to otherwise add another message to the conversation, the user can click on the text box for the incoming message, which will cause the device to display a soft keyboard (see, for example, UI 2300L of FIG. 23L). In some embodiments, user interface 2300K includes elements already discussed with respect to UI 2300H (FIG. 23H) and UI 2300D (FIG. 23D).

FIG. 23L illustrates an example of a user interface 2300L for displaying a set of outgoing messages between the user and the sender of the incoming message, and for composing a reply message. FIG. 23L shows a soft keyboard through which the user can reply to an incoming message, or to otherwise add a message to a conversation. In the example shown in FIG. 23L, the user replies with “Enjoy the trip!,” which is subsequently appended to the end of the displayed set of messages between the user and the other party. In some embodiments, UI 2300L includes elements already discussed with respect to UI 2300D (FIG. 23D) and UI 2300H (FIG. 23H).

FIGS. 30A-30B are flow diagrams illustrating an example of a process for displaying an incoming message while the device is in locked mode 3002 in accordance with some embodiments.

The device displays (3004) an incoming message (e.g., 2212 FIG. 23B) from a party (e.g., “Jane Doe” 2210) to a user of the device on the touch screen display while the device is locked. In some embodiments, the incoming message is a Short Messaging Service (SMS), Multimedia Messaging Service, Enhanced Messaging Service (EMS), eXtensible Messaging and Presence Protocol (XMPP) message.

In some embodiments, the device displays (3006) a portion of the incoming message (e.g., 2212) on the touch screen display while the device is locked and a long-message indicia (e.g., an ellipsis, “ . . . ” 2211) if the incoming message is longer than a predefined length. The device displays (3008) the incoming message in its entirety on the touch screen display while the device is locked if the incoming message is equal to or less than the predefined length.

In some embodiments, while the device is locked, the unlock icon (e.g., “Slide to unlock” 306 FIG. 23A) is changed (3010) to a view icon (e.g., “Slide to view” 2214, FIG. 23B) when displaying the incoming message. The unlock icon may have a “Slide to unlock” or similar label. The view icon may have a “Slide to view” or similar label.

Operations 3006 and 3008 (displaying the message) can happen either before or after operation 3010 (adaptively displaying the view icon and the unlock icon.).

In some embodiments, if no user selection of the view message icon is detected within a predetermined period of time, the device ceases (3012) to display the incoming message on the touch screen display; and changes (3012) the view icon (e.g., 2214) back to the unlock icon (e.g., 306, FIG. 23A).

In response to detecting a user request (e.g., finger gesture 2213, FIG. 23B) to view the incoming message, the device immediately displays (3014) a set of messages between the user of the device and the party in a chronological order (e.g., UI 2300D FIG. 23D). The set of messages includes the incoming message (e.g., 2216).

In some embodiments, after the user sends a reply to the incoming message, the device automatically reverts to locked mode. In some other embodiments, after the user sends a reply to the incoming message, the device reverts to locked mode after a predefined period of time elapses.

In some embodiments, if no user request to view the incoming message is detected within a predetermined period of time, the device ceases (3016) displaying the incoming message on the touch screen display after the predetermined period of time. For example, in FIG. 23B, if the device does not detect a request to view the incoming message (e.g., a finger gesture 2213 on the view icon 2214), the device ceases to display the message (e.g., 2212) on the touch screen display.

In some embodiments, after ceasing to display the incoming message, the device displays (3018) a message alert (e.g., 2302 FIG. 23C) on the touch screen display. In the example shown in FIG. 23C, the message alert 2302 includes an identifier of the party and a time indicator for the incoming message.

After ceasing to display the incoming message, in response to detecting a user request (e.g., a finger gesture 2304 on the “Slide to unlock” icon 306 FIG. 23C) to unlock the device, the device is unlocked (3020). Furthermore, in response to detecting a user selection of an instant messaging icon, the device displays (3022) a list of instant messaging conversations. The list includes an unread message indicia (e.g., 2267 FIG. 23F) adjacent to the conversation between the user of the device and the party.

In some embodiments, if no user request to view the incoming message is detected within the predetermined period of time, the device marks (3024) a conversation that includes the incoming message as containing at least one unread message. Operations 3018, 3020, 3024 may happen in any order.

FIGS. 31A-31C are flow diagrams illustrating an exemplary process 3200 for displaying an incoming message to the user of the device when the device is unlocked (3202), in accordance with some embodiments. The device displays (3204) a portion of an incoming message from a party to a user of the device, a view icon (e.g., 2230 FIG. 23I), and a long-message indicia (e.g., “ . . . ” 2229) on the touch screen display if the incoming message is longer than a predefined length. In some embodiments, if the incoming message is longer than the predefined length the device also displays a scroll indicator (e.g., 2232 FIG. 23I) for viewing the entire message. There may also be a close icon (e.g., 2228) for closing the message.

The device displays (3206) the incoming message (e.g., 2218 FIG. 23E) from the party to the user of the device and a reply icon (e.g., 2222) on the touch screen display if the incoming message is equal to or less than the predefined length. For example, in UI 2300E, the entire message 2218 (“Hello! Free for lunch today?”) is displayed. In some embodiments, there may also be a Close icon (e.g., 2220) in addition to the reply icon (e.g., 2222).

In response to detecting user selection of either the view icon (e.g., 2230 FIG. 23I) or the reply icon (e.g., 2222 FIG. 23E), the device immediately displays (3208) a set of messages between the user of the device and the party in a chronological order (e.g., 2223 FIG. 23H). The set of messages includes the incoming message (e.g., 2223-1).

In some embodiments, in response to detecting a user selection of the reply icon (e.g., 2222 FIG. 23E), the device displays (3210) a soft keyboard, a text box, and a send icon on the touch screen display, in addition to displaying the set of messages (e.g., 2223).

In some embodiments, the device displays (3212) the incoming message (e.g., 2218 FIG. 23E) or a portion thereof (e.g., 2225 FIG. 23I), either the view icon (e.g., 2230 FIG. 23I) or the reply icon (e.g., 2222 FIG. 23E), and a close icon (e.g., 2220 FIG. 23E, 2228 FIG. 23I) on the touch screen display for a predetermined period of time.

If no user selection of the view icon, the close icon, or the reply icon is detected within the predetermined period of time, the device ceases (3214) to display the incoming message or a portion thereof, either the view icon and the reply icon, and the close icon on the touch screen display after the predetermined period of time

In some embodiments, after ceasing to display the incoming message or portion thereof, either the view icon and the reply icon, and the close icon, in response to detecting user selection of an instant messaging icon, the device displays (3216) a list of instant messaging conversations. The list includes an unread message indicia (e.g., 2206 next to the first conversation on FIG. 23J or 2206 next to the first conversation on FIG. 23F) adjacent to the conversation between the user of the device and the party.

In some embodiments, if no user selection of any of the view icon, the close icon, or the reply icon is detected within the predetermined period of time, the device marks (3218) a conversation that includes the incoming message as containing at least one unread message.

In some embodiments, the device displays (3220) the incoming message (e.g., 2218 FIG. 23E), either of the view icon (e.g., 2230 FIG. 23I) and the reply icon (e.g., 2222 FIG. 23E), and a close icon (e.g., 2220) on the touch screen display for a predetermined period of time.

In response to detecting user selection (e.g., a finger tap gesture) of the close icon (e.g., 2228 FIG. 23I) within a predetermined period of time, the device ceases (3222) to display the incoming message or portion thereof (e.g., 2225, FIG. 23I), either the view icon (e.g., 2230 FIG. 23I) or the reply icon (e.g., 2222 FIG. 23E), and the close icon (e.g., 2228 FIG. 23I) on the touch screen display.

In some embodiments, after ceasing to display the incoming message or portion thereof, either the view icon (e.g., 2230 FIG. 23I), and the reply icon (e.g., 2222 FIG. 23E), and the close icon (e.g., 2228), in response to detecting a user selection of an instant messaging icon (e.g., icon 141, FIG. 4, in a user interface that displays application icons), the device displays (3224) a list of conversations (e.g., FIG. 23J). The list includes an unread message indicia (e.g., 2206) adjacent to the conversation between the user of the device and the party if the incoming message is longer than the predefined length (e.g., 2229 FIG. 23J).

In some embodiments, after detecting the user selection of the close icon (e.g., 2228 FIG. 23I), the device marks (3226) a conversation that includes the incoming message as containing at least one unread message if the incoming message is longer than the predefined length (see FIG. 23J). Otherwise, if the incoming message is equal to or less than the predefined length (e.g., 2218, FIG. 23E), the device marks (3208) the conversation that includes the incoming message as containing no unread messages (see FIG. 23G).
